GPU for “3D VDI” – Vendor Comparison: Soft / Shared / Dedicated / vGPU

A high-level ‘graphics acceleration’ comparison section has been added to the Desktop Virtualization category of the ‘Matrix’ (in addition to the previously covered aspects (all listed below). Which vendor can provide software GPU, shared GPU or ‘GPU pass-through’ capabilities? What levels of OpenGL or DirectX are supported? The comparison includes e.g. VMware’s vSGA, vDGA; Citrix XenDesktop’s HDX 3D Pro capabilities including vGPU support for NVIDIA’s Grid GPUs (K1 and K2) as well as Microsoft‘s RemoteFX capabilities. To go directly to the “VDI Comparison View”

Stateless desktops, hotels and floating rooms …

Eyes glaze over, the meaningless automatic nodding starts and you can feel the person’s mind is miles away … yes, I admit, I had several such fruitless attempts of explaining the concept and benefits of using ‘stateless versus dedicated desktops’.   The inconsistency of todays “VDI” terminology doesn’t help and that includes the description of the relationship between the user and the desktop image. Stateless desktops are often also referred to as ‘non-persistent’, ‘pooled’ and ‘dynamic’

Maximums and sizing guidelines for VMware View, XenDesktop (on vSphere) and Virtual Bridges VERDE

When we introduced a building block approach to our reference architecture many questions from the wider team revolved around the scaling maximums and limitations of the respective desktop virtualization solution in order to create valid configurations and correctly sized building blocks. It became quickly apparent that while e.g. in VMware’s case vSphere maximums were well documented, the virtual desktop specific guidelines are scattered around in different documents, some are not listed at all and others

How to configure 3D and Aero for VMware View 5 – and what is the overhead of doing so? (IBM VDI RA Part 3)

As you probably know, View 5 (in conjunction with vSphere 5) introduced has a software-based GPU function that gives users basic DirectX and OpenGL capability without the use of a physical GPU (like e.g. Citrix’s HDX3D GPU-passthrough requires). Typical target use cases include Aero and low-end 3D animations, not “high-end” 3D engineering application. One of the questions I’ve been regularely asked is “what amount of overhead does this create? As we have no physical GPU in this

VDI – Success or Failure? – or – Why “VDI-bashing” is popular….

I have to admit that it is slightly irritating to fly home from ‘yet another’ client meeting and stumble across ‘yet another’ discussion (OK, let’s call it rant) about VDI on twitter or blogs. Especially when the meeting was actually a positive one that included VDI – so yes – my opinion upfront – there is such a thing as ” successful VDI” (and note that I’m absolutely not saying all projects are) There are good and

(IV) Rethinking my View of VMware’s End-User Capabilities – Is View 5 a Game Changer?

(This is Part 4 of the ‘Real-World VDI’ series – see Part 1 “Multi-Vendor Stack, Part 2 “High-End Graphics”, Part 3 “Cost” and Part 5 “Future of VDI”) The announcements at VMworld caused me to adjust my view of VMware’s end-user capabilities and vision. So what did VMware announce and why will it impact the current pattern and future directions? There are two streams: The immediate impact with the latest VMware View 5/vSphere 5 product announcement and The

(II) Real-World VDI – Advanced Graphics: DirectX, OpenGL with HDX & PCoIP

(This is Part 2 of the ‘Real-World VDI’ series – see Part 1 “Multi-Vendor Stack, Part 3 “Cost”,  Part 4 “Recent Announcements” and Part 5 “Future of VDI”) While most clients initially enthusiastically agree to address first the “low hanging fruits” of VDI, almost without exception I had the “dreaded question” come up consistently in the first meeting: “I have this user group with high-end graphics, video conferencing/3D graphics/engineering application (replace this with your graphics

Citrix announces XenServer 6 Beta – The ‘beginning of the end’ for XenCenter?

Citrix announced the public beta for their next version of XenServer 6.0. There are various changes and new features which you can review HERE but I have listed some of the relevant ones below. Some of the key changes are around Citrix’s cloud capabilities (as expected). What strikes me is the overwhelming ‘generosity’ of promoting another vendor’s management platform as part of their own announcement. So all of us aware of the Microsoft’s SCVMM 2012
